The youngest personality on the list is 17-year-old activist Malala Yousafzai, while the oldest is wildlife broadcaster Sir David Attenborough, aged 88.

There are 147 females on the list.

Joanne Milner, chief executive at Debrett’s, said: “We are delighted to announce this year’s Debrett’s 500. It’s a fascinating mix of people, and not entirely who you might expect.

“Every individual, though, demonstrates outstanding qualities of influence, achievement and inspiration. I think now is the perfect time to consider how we can inspire the next generation of influencers, so that we can ensure that everyone, regardless of their background, has an equal opportunity to succeed.

“The Debrett’s Foundation is our way of addressing this issue.”

The foundation supports social mobility in a bid to ensure that the next generation of leaders and influencers are from all backgrounds.
